World AIDS Day (December 1st)

Universal Access and Human Rights

 


Started on 1st December 1988, World AIDS Day is about raising money, increasing awareness, fighting prejudice and improving education. The World AIDS Day theme for 2010 is 'Universal Access and Human Rights'. World AIDS Day is important for reminding people that HIV has not gone away, and that there are many things still to be done.
According to UNAIDS estimates, there are now 33.3 million people living with HIV, including 2.5 million children. During 2009 some 2.6 million people became newly infected with the virus and an estimated 1.8 million people died from AIDS.1
The vast majority of people with HIV and AIDS live in lower- and middle-income countries. But HIV today is a threat to men, women and children on all continents around the world.

HIV Infection
HIV stands for Human Immuno Deficiency Virus. As the name suggests this virus affects by creating deficiency of immunity in host body. This virus attacks the immune system of the person and makes it weaker. The body loses its mechanism to fight the infections. Hence once infected with HIV, the body becomes an easy target of infectious diseases. As the antibodies created by body fail to counter check the growth or foreign infections, the diseases becomes severe and in many cases it may prove fatal. HIV infection is very serious concern to human community as the victim becomes susceptible to many infections and diseases. The treatment and medication available for HIV infection is limited.

Causes
HIV may spread from one person through unsecured sexual intercourse, use of contaminated needles and syringes, through blood transfusion where the donor is infected and other media through which it may enter the blood stream. An infected mother may transfer the virus to her new born or later via breast feeding
As the symptoms of HIV infection are not prominent it is very hard to make out whether a person needs attention against the infection. However, unknowingly an already infected person may still transfer the virus through sexual intercourse. HIV infection is also prevalent in drug addicts who tend to use same syringe to take drug shots
HIV infection grows slowly and after infection it may take up to three months to show symptoms or positive results in blood tests. Due to lack of knowledge, people’s carefree and casual attitude towards sex, this disease has taken its worst toll in many parts of the world

HIV Infection Symptoms and Signs
HIV itself is not a disease causing virus however it facilitates other agents spread diseases. It mars the body’s mechanism to fight against foreign agents. An HIV positive person shows symptoms like fever, diarrhea, frequent yeast infection in vagina, headaches, mouth sores, fungal infections, loss of muscle elasticity and various forms of allergies.
The best indication is when a series of medication fail to treat the symptoms listed above. For example a wound may not heal for long even after regular medication and proper bandaging. When the symptoms last longer than normal known period, it should be taken as a positive indication.
The most deadly consequence of infection could lead the person to develop AIDS. Other consequences include fatal diseases like cancer, chronic wasting, dementia, lipodystrophy, candidiasis, cytomegalovirus, protozoan infections, MAC, pneumocystis, salmonella bacterial infection, tuberculosis and toxoplasmosis.

Detection
There are two most common tests available to test HIV Infection
ELISA test
HIV Western Blot Test
These tests detect the virus by looking for the presence of antibodies generated by the body to fight against the infection by HIV. Those who suspect infection and test show negative results, should undergo tests again after 3 months and should do the test at least 3-4 times to be sure. In case these test show positive results, one should seek medical attention. The doctor might ask for other test to ensure that the diagnosis of HIV infection were correct.
A simple test like WBC count may suggest the infection. If the platelets are lower in number, the body is losing its immunity to fight infections. A count less than 500 cells/ml is dangerous.

Most prevalent and effective way of being safe is prevention. However, in cases where the infection is already evident, one must seek medical attention. Drug therapy is recommended for patients with suppressed immunity. Pregnant women, kidney patients or patients with neurological disorders need special treatment. As the virus is known to become resistant to medication a dose should never be missed. People with HIV infection need to be education to ensure that they don’t spread the virus

Precautions
Avoid unhealthy sexual participation and always use protection. It is very important that you know your partner’s medical history
Avoid injected drugs and if indispensable use disposable and new syringe for every shot
Avoid oral, vaginal or anal contact with HIV infected person
People with the infection should not donate blood, plasma, sperms, eggs, organs and should not exchange genital fluids

Love Quotes

Here are some of the anonymous love quotes and sayings from ...anonymous people:
God gave us two ears to hear, two eyes to see and two hands to hold. But why did God give us only one heart? Because he wants us to find the other one.
Is the word "love" important?
I don't know but for me, you are more important.
Do you know why?
Because how can I say "I love you" if you're not here.
One time I asked you, "why do you love him so much?" you told me, "because we've been together for so long", I got annoyed because you're numb, you didn't even think that the time you were together, it took me longer to have waited for you.
No matter how many times I get hurt because of you, I won't leave you. Because even if I have a hundred reasons to leave you, I'll look for that one reason to fight for you.
An angel asked me "why are you say?", thinking of you I answered "because I miss her", then I heard the angel giggle...I looked up and began to smile and said "oh, it's you!"
They said that if you are unable to sleep, it's because there's someone thinking about you...surely that person misses you. That's why if you can't sleep, sorry, I can't help it.
St. Peter scold me saying "son, where have you been?" And he saw me with you and asked "why are you with that person?" and I said to him "sorry St. Peter, I thought it was heaven."
Back then I thought I was the unluckiest person in the world, then I looked at you and smiled. Why? Because no matter how unlucky I was, it was worth it because of you.
They said love is like a toy. When it's new, it's so loved and don't want to lend it to others, doesn't want anybody touching it and don't want to let go of it. Yes, it's being taken care of, but the down side is, it's being played so many times.
When the time comes for you to leave me, just say so! I can let you go. But let me embrace you while saying, " You'll go back to me, okay! When he leaves you."
In love, the past is not important, but the present. Experience is more relevant than the pain you went through. The only thing that will make it stronger is forgiveness and not the retorting of sin.
God is so good. He knows where a person will be happy, where they can love and be loved, where heaven on earth is. Now I know why he put me near you.
Any guy can love a thousand girls...but only a rare guy can love one girl in a thousand ways
In every girls life there will always be those three guys...the one she loves, the one she hates, and the one she can’t get enough of...and in the end...they're all the same guy.
Find that guy that will pick up every piece of your shattered heart & put it back together; Replacing it with a piece of his.
I love you not because I need you, I need you because I love you
If you asked me how many times you have crossed my mind, I would say once, because you never really left…
They say love hides in every corner, and then I must be walking in circles
Others will say, loving someone is tiring: sometimes happy, sometimes you'll cry! 
They said I'd have enough someday.
I said to them, that is not true, you know why? "When does ever a person had enough if his love is true.."
I wish I had never known you. I was happy before even when you were not there yet. Unlike now, you make me suffer, I know that you didn't mean to have known me. Me too, I wasn't planning on loving you.
No matter what words were used or what meaning about love was delivered, love quotes were said and written out of inspiration and to emphasize each person’s purpose for living…and that is to give love.

Sri Lanka

Sri Lanka (English pronunciation: /sriˈlɑːŋkə/, /sriˈlæŋkə/, or /ʃriˈlɑːŋkə/;[8][9] local pronunciation: [ˌɕriːˈlaŋkaː]; Sinhala: ශ්‍රී ලංකා, Tamil: இலங்கை), officially the Democratic Socialist Republic of Sri Lanka and known as Ceylon (pronounced /sɨˈlɒn/, /ˌseɪˈlɒn/, or /ˌsiːˈlɒn/) before 1972, is an island country in South Asia, located about 31 kilometres (19.3 mi) off the southern coast of India.


As a result of its location in the path of major sea routes, Sri Lanka is a strategic naval link between West Asia and South East Asia.[citation needed] It has also been a center of the Buddhist religion and culture from ancient times and is one of the few remaining abodes of Buddhism in South Asia, including Ladakh, Bhutan and the Chittagong Hill Tracts, as well as being a bastion of Hinduism.[10] The Sinhalese community forms the majority of the population; Tamils, who are concentrated in the north and east of the island, form the largest ethnic minority. Other communities include Moors, Burghers, Kaffirs, Malays and the indigenous Vedda people.

The country is famous for the production and export of tea, coffee, coconuts, rubber and cinnamon - which is native to the country.[11] The natural beauty of Sri Lanka's tropical forests, beaches and landscape, as well as its rich cultural heritage, make it a world famous tourist destination.[citation needed] The island also boasts the first female Prime Minister in the modern world, Sirimavo Bandaranaike.[12]

After over two thousand years of rule by local kingdoms, parts of Sri Lanka were colonised by Portugal and the Netherlands beginning in the 16th century, before control of the entire country was ceded to the British Empire in 1815.[citation needed] During World War II, Sri Lanka served as an important base for Allied forces in the fight against the Japanese Empire.[13] A nationalist political movement arose in the country in the early 20th century with the aim of obtaining political independence, which was eventually granted by the British after peaceful negotiations in 1948.

The island of Sri Lanka lies in the Indian Ocean, to the southwest of the Bay of Bengal. It is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. According to Hindu mythology, a land bridge to the Indian mainland, known as Rama's Bridge, was constructed during the time of Rama by the vanara architect Nala. Often referred to as Adam's Bridge, it now amounts to only a chain of limestone shoals remaining above sea level.[20]


According to colonial British reports, this is a natural causeway which was formerly complete, but was breached by a violent storm in 1480.[21] The island consists mostly of flat-to-rolling coastal plains, with mountains rising only in the south-central part. Amongst these is the highest point Pidurutalagala, reaching 2,524 metres (8,281 ft) above sea level.

The climate of Sri Lanka can be described as tropical and warm. Its position between 5 and 10 north latitude endows the country with a warm climate moderated by ocean winds and considerable moisture. The mean temperature ranges from about 16 °C (60.8 °F) in the Central Highlands, where frost may occur for several days in the winter, to a maximum of approximately 33 °C (91.4 °F) in other low-altitude areas. The average yearly temperature ranges from 28 °C (82.4 °F) to nearly 31 °C (87.8 °F). Day and night temperatures may vary by 4 °C (7.20 °F) to 7 °C (12.60 °F). During the coldest days of January, many people wear coats and sweaters in the highlands and elsewhere.

May, the hottest period, precedes the summer monsoon rains. The rainfall pattern is influenced by monsoon winds from the Indian Ocean and Bay of Bengal: as the winds encounter the mountain slopes of the Central Highlands, they unload heavy rains on the slopes and the southwestern areas of the island. Some of the windward slopes receive up to 2,500 millimetres (98.4 in) of rain each month, but the leeward slopes in the east and northeast receive little rain. Periodic squalls occur and sometimes tropical cyclones bring overcast skies and rains to the southwest, northeast, and eastern parts of the island.

Between December and March, monsoon winds come from the northeast, bringing moisture from the Bay of Bengal. Humidity is typically higher in the southwest and mountainous areas and depends on the seasonal patterns of rainfall, and places like Colombo experience daytime humidity above 70% all year round, rising to almost 90% during the monsoon season in June. Anuradhapura experiences a daytime low of 60% during the monsoon month of March, but a high of 79% during the November and December rains. In the highlands, Kandy's daytime humidity usually ranges between 70% and 79%.

The mountains and the southwestern part of the country, known as the "wet zone", receive ample rainfall at an average of 2,500 mm (98 in). Most of the east, southeast, and northern parts of the country comprise the "dry zone", which receives between 1,200 mm (47 in) and 1,900 mm (75 in) of rain annually. Much of the rain in these areas falls from October to January; during the rest of the year there is very little precipitation. The arid northwest and southeast coasts receive the least amount of rain at 600 mm (24 in) to 1,200 mm (47 in) per year.


Varieties of flowering acacias are well adapted to the arid conditions and flourish on the Jaffna Peninsula. Among the trees of the dry-land forests, are some valuable species such as satinwood, ebony, ironwood, mahogany and teak. In the wet zone, the dominant vegetation of the lowlands is a tropical evergreen forest, with tall trees, broad foliage, and a dense undergrowth of vines and creepers. Subtropical evergreen forests resembling those of temperate climates flourish in the higher altitudes. Forests at one time covered nearly the entire island, but by the late 20th century lands classified as forests and forest reserves covered around ⅓ of the land.[22]

The Yala National Park in the southeast protects herds of elephant, deer, and peacocks, and the Wilpattu National Park in the northwest preserves the habitats of many water birds, such as storks, pelicans, ibis, and spoonbills. During the Mahaweli Ganga Program of the 1970s and 1980s in northern Sri Lanka, the government set aside four areas of land totalling 1,900 km2 (730 sq mi) as national parks. The island has four biosphere reserves, Bundala, Hurulu Forest Reserve, the Kanneliya-Dediyagala-Nakiyadeniya, and Sinharaja.[23]

The national flower of Sri Lanka is the Nymphaea stellata (Sinhalese Nil Mahanel),[24] the national tree is the Ironwood (Sinhalese Na),[25] and the national bird is the Sri Lanka Junglefowl, which is endemic to the country.[26]

History

Paleolithic human settlements have been discovered at excavations in several cave sites in the Western Plains region and the South-western face of the Central Hills region. Anthropologists believe that some discovered burial rites and certain decorative artefacts exhibit similarities between the first inhabitants of the island and the early inhabitants of Southern India. Recent bioanthropological studies have however dismissed these links, and have placed the origin of the people to the northern parts of India[citation needed].


One of the first written references to the island is found in the Indian epic Ramayana, which described the emperor Ravana as monarch of the powerful kingdom of Lanka, which was created by the divine sculptor Vishwakarma for Kubera, the treasurer of the Gods.[27] English historian James Emerson Tennent also theorised Galle, a southern city in Sri Lanka, was the ancient seaport of Tarshish from which King Solomon is said to have drawn ivory, peacocks and other valuables. The main written accounts of the country's history are the Buddhist chronicles of Mahavansa and Dipavamsa.

Sri Lankan coin, 1st century CE.The earliest-known inhabitants of the island now known as Sri Lanka were probably the ancestors of the Wanniyala-Aetto people, also known as Veddahs and numbering roughly 3,000. Linguistic analysis has found a correlation of the Sinhalese language with the languages of the Sindh and Gujarat, although most historians believe that the Sinhala community emerged well after the assimilation of various ethnic groups.
From the ancient period date some remarkable archaeological sites including the ruins of Sigiriya, the so-called "Fortress in the Sky", and huge public works. Among the latter are large "tanks" or reservoirs, important for conserving water in a climate that alternates rainy seasons with dry times, and elaborate aqueducts, some with a slope as finely calibrated as one inch to the mile. Ancient Sri Lanka was also the first in the world to have established a dedicated hospital in Mihintale in the 4th century BCE. Ancient Sri Lanka was also the world's leading exporter of cinnamon, which was exported to Egypt as early as 1400 BCE. Sri Lanka was also the first Asian nation to have a female ruler in Queen Anula (47–42 BC).
Ancient Sri Lanka

Since ancient times Sri Lanka was ruled by monarchs, most notably of the Sinha royal dynasty that lasted over 2000 years. The island was also infrequently invaded by South Indian kingdoms and parts of the island were ruled intermittently by the Chola dynasty, the Pandya dynasty, the Chera dynasty and the Pallava dynasty. The island was also invaded by the kingdoms of Kalinga (modern Orissa) and those from the Malay Peninsula.

Buddhism arrived from India in the 3rd century BCE, brought by Bhikkhu Mahinda, who is believed to have been the son of Mauryan emperor Ashoka. Mahinda's mission won over the Sinhalese monarch Devanampiyatissa of Mihintale, who embraced the faith and propagated it throughout the Sinhalese population. The Buddhist kingdoms of Sri Lanka would maintain a large number of Buddhist schools and monasteries, and support the propagation of Buddhism into Southeast Asia.

Colonial era

British colonial Coat of arms of CeylonSri Lanka had always been an important port and trading post in the ancient world, and was increasingly frequented by merchant ships from the Middle East, Persia, Burma, Thailand, Malaysia, Indonesia and other parts of Southeast Asia. The islands were known to the first European explorers of South Asia and settled by many groups of Arab and Malay merchants.

A Portuguese colonial mission arrived on the island in 1505 headed by Lourenço de Almeida, the son of Francisco de Almeida. At that point the island consisted of three kingdoms, namely Kandy in the central hills, Kotte at the Western coast, and Yarlpanam (Anglicised Jaffna) in the north. The Dutch arrived in the 17th century. Although much of the island came under the domain of European powers, the interior, hilly region of the island remained independent, with its capital in Kandy.

The British East India Company established control of the island in 1796, declaring it a crown colony in 1802, although the island would not be officially connected with British India. The fall of the kingdom of Kandy in 1815 unified the island under British rule.

20th Century and the World Wars

European colonists established a series of tea, cinnamon, rubber, sugar, coffee and indigo plantations. The British also brought a large number of indentured workers from Tamil Nadu to work in the plantation economy. The city of Colombo was established as the administrative centre, and the British established modern schools, colleges, roads and churches that brought Western-style education and culture to the native people.

Increasing grievances over the denial of civil rights, mistreatment and abuse of natives by colonial authorities gave rise to a struggle for independence in the 1930s, when the Youth Leagues opposed the "Ministers' Memorandum," which asked the colonial authority to increase the powers of the board of ministers without granting popular representation or civil freedoms. Buddhist scholars[citation needed] and the Teetotalist Movement also played a vital role in this time.

During World War II, the island served as an important Allied military base. A large segment of the British and American fleet were deployed on the island, as were tens of thousands of soldiers committed to the war against Japan in Southeast Asia. It was expected that Sri Lanka would gain independence as part of India, as the Indian National Army created a 'Lanka Regiment' from the existent Sri Lankan diaspora. Indeed, A plan was made to transport them to Sri Lanka by submarine, to lead a liberation struggle there, but this was aborted.
Independence

The formal ceremony marking the start of self rule, with the opening of the first parliament at Independence Square.Following the war, popular pressure for independence intensified. The office of Prime Minister of Ceylon was created in advance of independence on 14 October 1947, Don Stephen Senanayake being the first prime minister. On 4 February 1948 the country won its independence as the Dominion of Ceylon. The island enjoyed good relations with the United Kingdom and had the British Royal Navy stationed at Trincomalee.

On 21 July 1960 Sirimavo Bandaranaike took office as prime minister, and became the world's first female prime minister and the first female head of government in post-colonial Asia. In 1972, during Sirimavo Bandaranaike's second term as prime minister, the country became a republic within the Commonwealth, and the name was changed to Sri Lanka.

Civil war

One of the aspects of the independence movement was that it was very much a Sinhalese movement. As a result, the Sinhalese majority attempted to remodel Sri Lanka as a Sinhalese nation-state. The lion in the national flag is derived from the banner of the last Sinhalese Kingdom, which, to the Sinhalese majority, is a symbol of their fight against British colonialism. One single strip of orange on the left part of the flag represents the Tamil population, and it is seen by many Tamil as a symbol of their marginalisation.[28]

In 1956, the Official Language Act (commonly known as The Sinhala Only Act) was enacted. The law mandated Sinhala, the language of Sri Lanka's majority Sinhalese community, which is spoken by over 70% of Sri Lanka's population, as the sole official language of Sri Lanka. Supporters of the law saw it as an attempt by a community that had just gained independence to distance themselves from their colonial masters.

The immediate (and intended) consequence of this act was to force large numbers of Tamil who worked in the civil service, and who could not meet this language requirement, to resign. An attempt to make Buddhism the national religion, to the exclusion of Hindu and Islam, was also made. Affirmative action in favour of Sinhalese was also instituted, ostensibly to reverse colonial discrimination against Sinhalese in favour of Tamil. Many Tamil, in response to this deliberate marginalisation, came to believe that they deserved a separate nation-state for themselves.

From 1983 to 2009, there was an on-and-off civil war against the government by the Liberation Tigers of Tamil Eelam (LTTE), a separatist militant organisation who fought to create an independent state named Tamil Eelam in the North and East of the island. Both the Sri Lankan government and LTTE have been accused of various human rights violations.

On 19 May 2009, the President of Sri Lanka officially claimed an end to the insurgency and the defeat of the LTTE, following the death of Velupillai Prabhakaran and much of the LTTE's other senior leadership.[29]
Post War

After the civil war was over, the government of Sri Lanka called for redevelopment of the nation. The final stages of the war left some 300,000 people displaced.[30] By 2 May 2010, 214,227 IDPs (74%) had been released or returned to their places of origin.[31]


Government and politics

The Supreme Court of Sri Lanka, Colombo.The Constitution of Sri Lanka establishes a democratic, socialist republic in Sri Lanka, which is also a unitary state. The government is a mixture of the presidential system and the parliamentary system. The President of Sri Lanka is the head of state, the commander in chief of the armed forces, as well as head of government, and is popularly elected for a six-year term.

In the exercise of duties, the President is responsible to the Parliament of Sri Lanka, which is a unicameral 225-member legislature. The President appoints and heads a cabinet of ministers composed of elected members of parliament. The President's deputy is the Prime Minister, who leads the ruling party in parliament and shares many executive responsibilities, mainly in domestic affairs.[32]

Members of parliament are elected by universal (adult) suffrage based on a modified proportional representation system by district to a six-year term. The primary modification is that, the party that receives the largest number of valid votes in each constituency gains a unique "bonus seat." The president may summon, suspend, or end a legislative session and dissolve Parliament any time after it has served for one year. The parliament reserves the power to make all laws.

On 1 July 1960 the people of Sri Lanka elected the first-ever female head of government in Prime Minister Sirimavo Bandaranaike. Her daughter Chandrika Kumaratunga served for a short period as the prime minister between August and December 1994 before being elected as president from 1994 to 2005 for 2 consecutive terms. The current president, who took office on 21 November 2005, and has been elected for two consecutive terms, is Mahinda Rajapaksa. The current prime minister, D. M. Jayaratne, took office on 21 April 2010.

Sri Lanka has enjoyed democracy with universal suffrage since 1931. Politics in Sri Lanka are controlled by rival coalitions led by the left-wing Sri Lanka Freedom Party, headed by President Rajapaksa, the comparatively right-wing United National Party led by former prime minister Ranil Wickremesinghe and JVP. There are also many smaller Buddhist, socialist and Tamil nationalist political parties that oppose the separatism of the LTTE but demand regional autonomy and increased civil rights. Since 1948, Sri Lanka has been a member of the Commonwealth of Nations and the United Nations.

It is also a member of the Non-Aligned Movement, the Colombo Plan, Asia-Pacific Economic Cooperation and the South Asian Association for Regional Cooperation. Through the Cold War-era, Sri Lanka followed a foreign policy of non-alignment but has remained closer to the United States and Western Europe.

The military of Sri Lanka comprises the Sri Lankan Army, the Sri Lankan Navy and the Sri Lankan Air Force. These are administered by the Ministry of Defence. During 1971 and 1989 the army assisted the police in government response against the Marxist militants of the JVP and fought the LTTE from 1983 to 2009. Sri Lanka receives considerable military assistance from Pakistan and China.[33]

Economy


The Colombo World Trade Center in Colombo.In the 19th and 20th Centuries, Sri Lanka became a plantation economy, famous for its production and export of cinnamon, rubber and Ceylon tea, which remains a trademark national export. The development of modern ports under British rule raised the strategic importance of the island as a centre of trade. During World War II, the island hosted important military installations and Allied forces. However, the plantation economy aggravated poverty and economic inequality.

From 1948 to 1977 socialism strongly influenced the government's economic policies. Colonial plantations were dismantled, industries were nationalised and a welfare state established. While the standard of living and literacy improved significantly, the nation's economy suffered from inefficiency, slow growth and lack of foreign investment[citation needed].

From 1977 the UNP government began incorporating privatisation, deregulation and the promotion of private enterprise. While the production and export of tea, rubber, coffee, sugar and other agricultural commodities remains important, the nation has moved steadily towards an industrialised economy with the development of food processing, textiles, telecommunications and finance. By 1996 plantation crops made up only 20% of export, and further declined to 16.8% in 2005 (compared with 93% in 1970), while textiles and garments have reached 63%.

The GDP grew at an average annual rate of 5.5% during the early 1990s, until a drought and a deteriorating security situation lowered growth to 3.8% in 1996. The economy rebounded in 1997–2000, with average growth of 5.3%. The year of 2001 saw the first recession in the country's history, as a result of power shortages, budgetary problems, the global slowdown, and continuing civil strife. Signs of recovery appeared after the 2002 ceasefire which died away following the beginning of war. Since the separatist war ended in May 2009 the Sri Lankan stock market has shown marked gains to be among the 3 best performing markets in the world.[38] The Colombo Stock Exchange reported the highest growth in the world for 2003, and today Sri Lanka has the highest per capita income in South Asia.
